My Anime Shopping Tree & My Cold Prodigy Wife!

Lloyd Ferrum's first existence in Riverio ended in mystery and failed vengeance. After dying peacefully at 80 on Earth with a Nobel Prize in Military Engineering, he awakens as his 19-year-old self—returned to Riverio years before his family's massacre. Bound to a brilliant but emotionally distant prodigy while society dismisses him as unremarkable, Lloyd discovers the 'Shopping Tree' system. Through it, he acquires spectacular, anime-inspired abilities and forges his path toward legendary power, reshaping a destiny he once failed to control.
